Is it possible to use python-social-auth's EmailAuth with drf-social-oauth2 for registration

I have a facebook authentication in my project, and I've set up some pipelines. So It would be nice for non-social email registration to also utilize these pipelines.

I tried adding EmailAuth to the authentication backends list, but I don't know what view to use now for registratioin.

So, is it possible (or reasonable) to use EmailAuth with drf-social-oauth2 for non-social registration, and if so, how do I do it?

You can integrate EmailAuth with drf-social-oauth2 by adding it to AUTHENTICATION_BACKENDS and using the same authentication pipelines.

Since drf-social-oauth2 lacks a native email registration view, create a custom API endpoint that registers users manually and authenticates them via the email backend. Then, expose this view in your urls

settings.py

AUTHENTICATION_BACKENDS = (
    'social_core.backends.email.EmailAuth',  # The email-based autentication
    'social_core.backends.facebook.FacebookOAuth2',  # Facebook login
    'django.contrib.auth.backends.ModelBackend',  # Default auth backend
)

custom registration view

from rest_framework.permissions import AllowAny
from social_django.utils import load_backend, load_strategy
from rest_framework.serializers import CharField, EmailField, Serializer

class EmailRegistrationSerializer(Serializer):
    email = EmailField()
    password = CharField(max_length=100)
    member_type = CharField(max_length=20)


class EmailRegisterView(APIView):
    permission_classes = [AllowAny]

    def post(self, request):
        serializer = EmailRegistrationSerializer(data=request.data)
        serializer.is_valid(raise_exception=True)

        strategy = load_strategy(request)
        backend = load_backend(strategy, "email", redirect_uri=None)
        user = backend.authenticate(
            response=serializer.data,
            backend=backend,
            strategy=strategy,
            request=request,
        )
        return Response({"detail": "User registered successfully"}, HTTP_201_CREATED)

urls.py

urlpatterns = [
    # ...
    path("auth/register/email/", EmailRegisterView.as_view(), name="email_register"),
]
